铁路骨干光传输网色散补偿问题研究

Study on Dispersion Compensation for Railway Backbone OTN

光纤色散是制约骨干光传输网的主要因素之一,为保证网络的可靠稳定,需要从网络设计、配置规划、安装调试、系统联调、系统验收及运行维护等方面做好色散补偿工作。本文结合铁路骨干OTN(光传送网)的1、4号环工程实践,介绍如何做好色散补偿工作,以供工程与运维工作参考。

Optical fiber dispersion is one of the main factors restricting the backbone transmission network.In order to ensure the reliability and stability of the network,it is necessary to make proper dispersion compensations in network design,configuration planning,installation and commissioning,system integration and test,system acceptance,and operation and maintenance.Combined with the engineering practice of railway backbone OTN(optical transmission network)Nol and 4 Ring,how to make proper dispersion compensation is discussed,offering reference for engineering and operation and maintenance work.
